Description
Element analyzer determinates the percentage eights of carbon, hydrogen, nitrogen, sulfur and oxygen of a sample. This information is important to help determine the structure of an unknown compound, as well as to help prove the structure and purity of a synthesized compound. It is based on the dynamic flash combustion of the sample followed by reduction, trapping, complete GC Separation and detection of the products by thermal conductivity detector.
